Since no table is given, I will explain how genes are inherited. After Mendel’s discoveries were
accepted, scientists realized that traits passed to offspring were the result
of genes being passed from parents to offspring. This is an example of the law
of inheritance. The genes that are passed down from the parents are being
shared by the offspring. It can be shown if the trait is recessive or dominant
from the parents’ gene. <span>Chromosomes
are inherited from the parents. One chromosome from each of 23 pairs came from
each of the parents. The two chromosomes of a pair (except for the sex
chromosomes) contain the same genes, but the genes have small differences. The
X and Y Chromosomes determine the organism’s sex. One chromosome pair - the sex
chromosomes - is unique. Typically females have two X chromosomes and males
have an X and a Y. Mothers always pass an X chromosome on to their children.
Whether the father passes on his X chromosome (leading to a pair of X
chromosomes) or his Y chromosome (making a mixed set) determines your sex. </span>
Answer:
A. Reduction in soil mass proved that plants get their food from the soil.
Explanation:
Plant take their food from the soil because in soil roots are present which absorb nutrients from the surrounding environment. The nutrients present in the soil comes from the decomposition of dead bodies of plants and animals and sometimes it is provided by the farmers in the form of fertilizers. The plant food contains nitrogen, phosphorus and potassium which is required in large amount for the better growth and development of the plant.
Answer: Reproduce, make energy, waste removal, react to changes
Explanation:
When an athlete eats more protein or amino acids than he or she needs, the extra amino acids are either used in building the muscle tissues or are used in energy expenditure.
Proteins are the macromolecules composed of amino acid as polymers. Protein is an essential food component because it helps in the synthesis and repair of body parts, it help in growth and development, and also provides fuel to the body.
Muscle tissues are the ones responsible for the movement of the complete body. The tissues are rich in blood supply. They are of three categories: skeletal, cardiac and smooth. Any movement in body is possible only because of the contractions and relaxations of muscles.
